SAFETY MESSAGES

For general safety information please refer to your M100E/M200E/M400E operator’s manual.

CAUTION

Never disconnect electronic circuit boards, wiring harnesses or electronic subassemblies while the unit is under power.

Printed circuit assemblies (PCAs) are sensitive to electro-static discharges too small to be felt by the human nervous system. Failure to use ESD protection when working with electronic assemblies will void the instrument warranty.

See Chapter 12 of your M100E/M200E/M400E operator’s manual for more information on preventing ESD damage.

NOTE

Technical Assistance regarding the use and maintenance of the any Teledyne Instruments product can be obtained by:

Contacting Teledyne Instruments’ Customer Service Department at 800-324-5190

Relay PCA 04523

Addendum to E-Series Operator Manuals

1. INTRODUCTION

This addendum documents a recent upgrade to the relay card installed in some of the M100E, M200E and M400E series analyzers. Specifically, a new relay PCA design, P/N 04523 replaces P/N 03955 and all of its versions in the following instruments.

It also corrects several errors related to the function of the relay PCA.

For those instruments, the information included in this addendum supersedes the information related to the relay PCA that appears in the chapters on Theory of Operation and Troubleshooting & Repair of your M100E/M200E/M400E operator’s manual’s.

Because the operator’s manual for each model family of the E-Series instruments is slightly different there is no direct correspondence between the sections and chapters of this addendum and those of the manual.

1.1. What’s the Same

In most respects the electronic operation of the Relay PCA 04523 is the same as Relay PCA 03955.

Both are used by the CPU to operate various AC and DC heaters that control the temperature of key components of the E-Series analyzers to such as sensor modules, reaction cells and converters as well as certain optional components such as IZS permeation tubes.

In both cases a set of configuration jumpers located on the relay card is used to configure the heaters for 110 VAC, 60 Hz vs. 230 VAC, 50 Hz operation.

Both Relay cards, based on commands from the CPU received over the I2C bus, energize/de-energize the various solenoid valves used to control the sample gas path of the analyzers (e.g. reference/measure valves; zero-span-cal valve options; IZS options; etc.)

Both distribute the AC and DC power to the various electrically powered components and assemblies for the instrument.

Both include a special watchdog circuit watches that will automatically shut of all valves as

well as turn off the UV Source(s) and all heaters should either the CPU cease issuing commands or the I2C bus fail. In both cases the sample pump will continue to run.
